STAKE SOCKET.

Application filed March 1, 1927. Serial No. 171,886.

This invention relates to stake sockets for the face of the socket so that the stake can be removed laterally from the socket, this being a much simpler and easier method espec ally when there is a heavy lateral load thrust against the stake, binding it in the socket.

1 In this type of socket the side walls are subject to breakage, since the front does not integrally bind the sides together agalnstthe spreading action imparted by the stake under load. Then too, it is necessary that the door be quickly and easily releasable when the load wedges the stake in the socket thereby causa ing the stake to bear heavily against the door and alsothat the door may be positively held shut when the socket is in service.

It is therefore an object of this invention to provide in a stake socket of the releasing door type, a swinging latch bar adapted to engage over the face of the door, the end of the latch bar engageable into the frame so. as to be frictionally held and the bar to be positively held across the face of'the door against accidental displacement, the engagement of the bar end with the frame springing the bar slightly to aid frictional engagement across the door face.

Another object is to provide a latch bar of this nature for use in conjunction with a hinged door, the latch pivoted to the socket and adapted to spring over a lug on the face of the door at the time that the bar end is set within the frame, the releasing being accomplished by exerting a slight lateral pull on the handle to bring the bar back over the lug.

Another object is to provide reinforcing means on the inner face of the door adapted to engage one of the socket side walls to prevent spreading of the side walls, this engagement in conjunction with the hinged connection of the door, reinforcing and bracing the side walls of the socket when the door is closed and the socket is in service.

Still another object is to provide a socket door of this nature in which a latch bar is pivoted to the socket frame and adapted to be aligned with an opening in the door when it is desired to release the door and to engage over the portions of the door at each side of the opening when the door is in service or closed position.

Further objects and advantages will be more fully set forth in the description of the accompanying drawings forming a part of th1s specification, in which: I I

F gure 2 is a plan view of the socket. Figure 3 1s a side View thereof more clearly illustrating the latching means for the door.

Figure 4 is adetailed sectional view taken on line 44, Figure 3, detailing the lugson the door for reinforcing the socket-side walls.

-F 1gure 5 is adetailed sectionalview taken on hne 5-5, Figure 3, detailing the pivot for the latch bar.

Referring to the drawings,the socket comprises a frame 1 and a door 2 hinged to the frame. The socket frame is attached to the truck structure 3 by means of bolts 4 engaging,

the truck structure through flanges 5 at each side of the socket frame. Pairs of horizontally disposed side wall reinforcingribs I 6 are formed at each side of the socket frame and a flange 7 extends from the rear'of the socket so as to overhang the top of. the 'truck frame. x

A square closure is formed by side walls 8 formed integral with and projecting out from the truck engaging portion 9 of the frame. The portion 9 forms the rearwall of the closure and the door 2 closes the face side thereof. A bottom 11 also integral with the socket frame sustains the stake 12 in the closure. I

The door 2 is hinged to a frame side wall I as at 13 in a conventional manner. A latching bar 14- for the door is pivotally'attached to the opposite wall of the socket in such manner as to be swung vertically across the door face. Pivotal attachment'for the bar is through a bolt 15 extending through a boss '16 formed on the socket side Wall (see Figure notch or slot 18 is formed on the lower side of the overhanging portion, the slot being disposed in the path of movement of the swinging upper end 19 of the latch bar. The taper of the slot causes the bar end to be frictionally gripped upon insertion therein, the wide end of the slot being at the point of bar end entrance. Setting of the bar in locked position is further accomplished by a slight disalignment of the slot from the path of movement of the bar end, movement of the bar end into the slot causing the bar to be sprung laterally, thereby more firmly maintaining it in the slot. The tapered slot may be said to be just beyond the outer face of the door when the door is shut, this arrangement providing that the bar is in contact with the door across its entire face. The door is slightly thickened at the top thereof so as to cause it to bear against the latch when the latchbar is sprung outward at its upper end. The door as shown may be of a ribbed structure, this, however, being immaterial except for purposes of manufacture and weight. i

The lock bar is further maintained in its locked position by virtue of its engagement with a lug 20 (see Figure t) formed on the face of the door below the bar pivot. The lug 20 may be termed a catch since it functions to prevent accidental return or release movement of the bar from its engagement with the tapered slot. The bar strikes the inclined face 21' of the lug and snaps over the lug, with easy return thereof prevented by means of the engagement of the bar with a second or nore abruptly inclined surface 22ofthe lug. The release of the door is accomplished by pulling outward on the lower end of the bar and forcing it back over the lug, this movement of the bar disengaging it from the tapered slot, and further movement aligning the bar with the release opening in the door, this allowing the door to be swung unobstructed past the then horizontally disposed latch bar.

Means for reinforcing the socket are provided on the door inner face for the purpose of preventing spreading of the socket side walls when heavy pressures are imparted on the stake inserted in the socket. The reinforcement'is in the form of lugs 01' projections 23 formed integral with the door at its latching end above and below the release opening inthe door. These projections are provided with flat inner faces positioned at right angles to the door inner face for engagement with the outer face of the side wall when the door is swung shut, the outer walls being inclined to further strengthen the lugs. The two side walls of the socket may be said to be tied together by the door when the door is shut and the socket is in use, since the door has a hinged connection to one side wall and the projections 23 overhang the for locking thedoor, andthe door releasable by aligning the bar with the slot.

2. A stake socket of the class described,

comprising, a stake end closure frame open at one side, a door hinged tothe frame'for closing said open side, sald door having a slot atthe swinging end thereof, a latch bar pivoted to said frame at a point straddled by the slotted door end and align'able with the slot, and said frame having a notch disposed in'the path of swing of the end of the bar so as to frict-ionally hold the bar end when the bar is swung from alignment wit'h: the slot to locked position acrossthe face of the door.

3. A stake socket of the class described, comprising, a socket frame'open at onesi'de, a stake release door for closing said open side, and a latch bar mounted on the frame and adapted to engage across thewidth of the door outer face for locking the door in closed position.
